I worried about whether the time investment would be worth it when I was getting into tiling window managers (using chunkwm on Mac), but it has paid dividends and was totally worth it. The thing that helped me over the hump was setting a background image with the key commands for a little while, until it felt like second nature. A couple of years in now the key commands I’m pressing seem subconscious, almost like when entering a typo and looking and down at the keyboard and becoming disoriented. It’s weird.
